HI Guys,

is it possible to let the students enter a linear equation system, where they have to choose the variable names themselves??

I am at a loss....

Yes, you can.

What properties of the system will you test?, There is the "substitution equivalence" test, or you could "solve" the student's system and look at the solutions.

Hi Chris,

I want to test both but I don't even know which input type I have to choose.

Exercise

I own 100 coins totaling 100 euros. it is only 1-euro coins, 2-euro coins and 50-cent coins. I have six times as many 50-cent coins as 1-euro coins. What is the equation system in the standard form to be considered here?

The solution is for example:

x + y + z = 100

x + 0.5y + 2z = 100

y - 6x = 0

I hope this helps

A good approach is to import the STACK demo course into your Moodle site (It comes with STACK in the samplequestions folder). Then work through some of the examples, and when you find one like what you are trying to do, edit the question to see how it does it.

There is a question just like you are trying to make in https://stack2.maths.ed.ac.uk/demo2018/mod/quiz/view.php?id=742 (you can self-register on that site.)

Dear Tim,

when I go to the link, the page "Demonstrating STACK (v4.3)" appears and no specific task. Where can I find this?

We have already downloaded the demo course. But I have not found a suitable task that fits my problem. I need the code for the task. At a finished task, I do not see how I have to build it and what input type and answer test I have to choose.

Can you help me again?
